The picture on the front cover of 0' Shaughnessy Dam 
was taken on June 7, 1923, before the dam was raised 
an additional 85.5 feet. 



In the 75th year since the first lands were acquired for the 
Hetch Hetchy Water and Power system, and in the midst of a very 
dry year, it is fitting to recognize the foresight, industry 
and dedication of the people who conceived, built and operate 
that system. One and three-quarter million San Francisco Bay 
Area residents receive a supply of first quality water from 
Iletch Hetchy. How did it all come about? 

The Metropolitan Bay Area of 1901 consisted of a San Francisco 
of 350,000 population, and a collection of small, quiet towns 
around the Bay. Booming growth, a high level of civic pride, 
and t he belief of every citizen that San Francisco was to be 
the leading metropolis of the Pacific Coast were the keynotes 
of the times. 

Some dissatisfaction with the commercial supplier, the Spring 
Valley Water Company, prevailed, occasioned by high rates, 
periodic shortages and recurring water quality problems. That 
dissatisfaction had prompted language in the Charter enacted 
in 1900, setting as a goal the acquisition and construction of 
a municipally owned water supply system. What was needed was 
a plentiful, high-quality water source that would meet the 
area's need for at least 100 years. Looking east to the Sierra 
Nevada, the planners found such a source in Yosemite National 
Park. But the water was 150 miles awayl 

The "City that knows how" was determined that the water system 
would be built, and the first land was purchased, and water 
rights established, in 1901. The ensuing struggle for permis- 
sion to build a dam in Hetch Hetchy valley went on for years. 
When the United States Congress confirmed the City's right to 
proceed in 1913, construction commenced on the largest such 
project on the Pacific Coast up to that time. After 21 years, 
and the expenditure of some $100 million, the first water 
arrived at Crystal Springs Reservoir via the Hetch Hetchy 
aqueduct in 1934. The drama surrounding the leadership, poli- 
tics, and the engineering and construction effort involved in 
the project would be worthy of an epic novel, as expansion of 
the system to meet water and power demand continues down to the 
present . 

The large and complex system was designed to be built in incre- 
ments as demand increased. The master plan concept of a full 
gravity aqueduct system to Crystal Springs, established in 1912, 
has been followed as the system has grown through the years to 
the present capacity of 300 million gallons daily. As a by- 
product of the falling water, hydroelectric generating capa- 
bility of 340 megawatts has been constructed; a major economic 
asset for San Francisco. Additional elements of the system are 
planned for construction as the demand increases.

Today, the benefits of the Hetch Hetchy project are so matter- 
of-factly accepted that the public has granted the system its 
highest accolade: cheap, pure and plentiful water is taken for 
grant cd !

:. 




The last concrete in the original O'Shaughnessy Dam 
construction was poured in April, 1923, bringing the 
total to 398,000 cubic yards. The height of the dam 
was 226.5 feet above the original streambed and 344.5 
feet from the bottom of the foundation. It was 298 
feet thick at the base and 15 feet at the top. At the 
time it was constructed, it was the second highest dam 
in the United States, Arrowrock in Idaho winning by 
ten feet. Between 1934 and 1938 it was raised an 
additional 85.5 feet. 



HIGHLIGHTS 

Financially, the outcome of Hctch Hetchy's Water and Power 
system operation for 1975-76 was influenced by two major events 
which occurred during the year - one man-made and the other 
the result of a natural occurrence. 

Breakdown of wage negotiations for the upcoming fiscal year 
between City's crafts workers and the Board of Supervisors 
resulted in a 38-day strike by City employees including electri- 
cians, plumbers, carpenters, laborers, street cleaners, etc. 
who are members of the crafts union. The strike began March 
31, 1 ( .l 7 6 and ended on May 8, 1976. The public transit system 
was quickly brought to a halt when the Municipal Railway drivers 
joined the strike at the very outset. The importance of the 
Hetch Hetchy Water and Power system operation to the success or 
failure of the strike was not to be overlooked. It, too, was 
forced to shut down with all hydroelectric generators stopping 
production at 1400 hours on April 2, followed by complete 
cessation of water delivery to the San Francisco Water Depart- 
ment for domestic purposes. 

The drought brought on by the lack of precipitation in the 
winter of 1975-76, resulting in the smallest snow melt runoff 
from the Hetch Hetchy, Cherry and Eleanor Watersheds in the 59 
years of record, has left the three reservoirs at less than 
601 full at the end of the report year. In order to conserve 
as much water as possible for domestic use in the Bay Area, the 
average daily power draft at Kirkwood and Moccasin Powerhouses 
beginning June 1, 1976, was reduced to 300 million gallons per 
day to coincide with the Hetch Hetchy Aqueduct capacity and the 
anticipated San Francisco Water Department demand for the next 
several months. In addition, the power draft at Holm Powerhouse 
was reduced to 200 cubic feet per second in order to conserve 
water at Lake Lloyd so that, if later conditions require, such 
water can be directed into the Hetch Hetchy Aqueduct. 



Ill Till HETCHY ORGANIZATION AND F UNCTIONS 

Under policies established by the San Francisco Public Utilities 
Commission, the HETCII HETCHY WATER AND POWER DEPARTMENT and the 
BUREAU OF LI CUT, HEAT AND POWER serve the City and County of 
San Francisco in the dual function of operating department and 
service bureau. 

Iletch Iletchy is a municipally-owned system of storage reservoirs 
and aqueducts which collects water from the Tuolumne River 
watershed and delivers it to the San Francisco Water Department. 
As a by-product of falling water, Hetch Hetchy operates and 
maintains hydroelectric generating stations and high voltage 
transmission lines for the production and distribution of elec- 
tric energy. 

Through its Transit Power Division, Hetch Hetchy has funded, 
operated, maintained and provided improvements for the electric 
facilities of the San Francisco Municipal Railway since July 1, 
1969. 

In order to handle this additional responsibility, Hetch Hetchy 
assumed control of the equipment and personnel of the Overhead 
Lines and Motive Power Sections of the Municipal Railway. 

All of Hetch Hetchy' s expenses, including those of the Transit 
Power Division, are supported by water and power revenues. 

The Bureau of Light, Heat and Power administers contracts for 
furnishing electric, gas and steam services to municipal depart- 
ments and handles monthly billings. It also administers con- 
tracts for furnishing street lighting services and for operation 
and maintenance of City-owned street lighting. Financing, 
design and construction of City-owned street lighting improve- 
ments are under the jurisdiction of the Department of Public 
Works, and plans for these improvements must be approved by the 
Public Utilities Commission through this Bureau. The Bureau is 
financed by appropriations from municipal departments and gas 
tax funds. 

For fiscal year 1975-76, the Department administered budgeted 
funds for all purposes as follows:

P LANS FOR THE NliAR F UTURE 

Finns for future Ilctcli Hetchy construction are included in the 
City's current Capita] Improvement Plan. 

Projects which will be added next year will include the 
following: 

Cherry Eleanor Pumping Station 

We have studied the possibility of installing pumps at the 
Cherry end of the Cherry Eleanor Tunnel. This study determined 
that it was economically feasible to capture, for electrical 
generation, water which presently spills at Lake Eleanor during 
the runoff season. Preliminary design work will commence this 
year, while the necessary permits and approvals are being 
obtained. 

Moccasin Powerhouse Bypass 

Studies are planned to make improvements on Rattlesnake Creek 
and Rig Jackass Creek to permit the discharge of water from 
Priest Reservoir into the fletch Hetchy Aqueduct for use in 
times of emergency when Moccasin Powerhouse is not operative.

HETCH 1IETCHY WATER AND POWER SYSTEM 

REVENUE AND EXPENDITURES 

Revenue from Ketch Ketchy Water and Power operations is derived 
principally from two sources: 

1. Sale of electric power and energy to San Francisco Municipal 
departments, Modesto and Turlock Irrigation Districts in 
the San Joaquin Valley, and seven industrial customers. 

Kaiser Cement f ( Gypsum Corporation Santa Clara County 

Kaiser Aluminum d, Chemical Corporation Santa Clara County 

Lockheed Missiles and Space Company, Santa Clara County 

Tnc . 

General Motors Corporation Alameda County 

IBM Corporation Santa Clara County 

Liquid Air, Inc. Alameda County 

Norris Industries, Riverbank Stanislaus County 

2. Sale of water to the San Francisco Water Department. 

POWER SALES 

Gross sale of electric energy amounted to $20,224,183, up from 
$18,484,718 during 1974-75. Although this revenue appears to 
be a new record, it does not have the same significance as the 
record revenue of last year. The reasons are not so obvious 
without knowing the following: 

(1) Much of the increase is due to the very large amount 
of supplementary power and energy which City had to 
purchase for resale and which was resold to the 
customers at substantially the same high price at 
which it was purchased. 

(2) The offset to last year's record revenue in terms of 
expenditure for supplementary power and energy was 
only $99,734, whereas this year the offset is 
$4,389,319. Therefore, from the standpoint of net 
earnings, the department finds itself in a much less 
profitable financial position than that of last year. 

Power and energy delivered to all City Departments increased 
1.9% over the previous year, mainly the result of increased 
consumption at the San Francisco General Hospital where addi- 
tional power for construction of the new facilities nearly 
doubled the total requirements of 11,091,942 kilowatthours for 
1974-75. Consumption at the Airport, usually the single largest 
energy consumer among the City departments, has remained sub- 
stantially the same as 1974-75. The requirements for the San 
Francisco Water Department have again increased 9.31, reflecting 



more pumping required by the drought condition. The Municipal 
Railway showed a decrease of 12.21 in annual consumption over 
the previous year, largely as a result of the Muni shutdown 
during the City employees' strike. 

Power and energy delivered to Modesto Irrigation District, 
Hetch Hetchy's largest power customer, and to Turlock Irrigation 
District, the third largest, increased by 17.71 and 13.6% 
respectively this year. These increases in purchases clearly 
reflect the dry year operation of the Districts' own plant where 
power is derived from water stored behind Don Pedro Dam. 

The hope of exceeding the record generation of 1974-75 was 
effectively shattered by the drought and the strike. Instead, 
the opposite was achieved with the lowest production recorded 
in seven years of operation of the present project. By 
comparison, the 1975-76 total output of 1,640,671,000 kilowatt- 
hours is 20% less than the record output of 2,057,609,000 
kilowatthours for 1974-75. 

Hetch Hetchy power is sold to City Departments at cost, repre- 
senting a saving to taxpayers for 1975-76 of approximately $3.2 
million compared to the cost if supplied by the local investor- 
owned utility. 

One of the benefits resulting from the June 24, 1975 Amendment 
Agreement witli the Pacific Cas and Electric Company for wheeling 
Hetch Hetchy power to City's municipal customers was the reduc- 
tion in energy which City has to supply to compensate the 
Company for losses incurred in transmission and distribution. 
The data for 1975-76 indicates that 33,248,681 kilowatthours 
was delivered to the Company for this purpose, almost 41,000,000 
kilowatthours less than that required under the old agreements. 
This reduction in losses when sold to industrial customers at 
prices effective during the year returned to the City additional 
revenue in excess of $650,000. 

In last year's annual report, it was estimated that the new 
electric power rates which were scheduled to go into effect 
July, 1975 would increase Hetch Hetchy's power revenue for 1975- 
76 from sales to the municipal customers (including resale to 
Airport tenants) by one million dollars. Comparison of results 
for 1974-75 and 1975-76 has confirmed the accuracy of this 
prognostication. Another revision of the rates is scheduled 
for action by the Public Utilities Commission in July 1976. 
Adoption of the proposed rates will boost revenue from sales to 
private consumers and municipal users another $900,000 in the 
upcoming fiscal year. 

August 1975 marked the first month of higher rates for Hetch 
Hetchy power sold to the Modesto and Turlock Irrigation Districts 
under signed agreements with them dated May 22, 1973 and 
November 6, 1972 respectively. 



WATER SALES 

This past year, revenue from sale of water and standby service 
to the San Francisco Water Department was $6,550,000, $428,000 
less than cost to Hetch Iletchy.

WAT LR PRODUCTION AND TR ANSMISSION 

Prcci pitation recorded for the year at our measuring stations 
was 58°6 of the long term average. 

During the year, 70,086,900,000 gallons of water were diverted 
from the Tuolumne River watershed through the Hetch Hetchy 
Aqueduct to the San Francisco Water Department, representing 
71" oT the City's total customer consumption. In addition, 
237,693,456 gallons were delivered to the United States 
Atomic Lnergy Commission at Mocho Shaft of the City's Coast 
Range Tunnel for use at the Lawrence Radiation Laboratory at 
Livermore; 49,306,396 gallons were delivered to Groveland 
Community Service District in Tuolumne County from the Mountain 
Tunnel .

OF] R MING AND MAINTENANCE - MOCCASIN DIVISION 

IIPI. M POWERHOUSE UNIT NO. 2 GENERATOR 

At approximately D842 hours on Sunday, January 25, 1976, the 
13,800 volt stator winding of Generator No. 2 at Dion R. Holm 
Powerhouse failed. Preliminary investigation indicated that 
approximately 8 of the 216 coils had heen damaged. However, 
detailed examination following removal of the rotor assembly 
disclosed that a total of 16 coils would have to be replaced. 
Several of these coils were still functional, but dc high 
voltage testing showed that they would probably fail in a short 
time and were therefore deemed unacceptable for continued use. 
Portions of insulation on 4 field poles were also damaged by 
hot metal splatters from the stator windings when the failure 
occurred, requiring re-insulation of the affected area. All 
repair work was performed by departmental personnel, with 
supervision provided by the field engineers from All is-Chalmers , 
the generator manufacturer. The repairs were completed and the 
generating unit returned to service by the middle of March. 

A board of inquiry consisting of the senior electrical engi- 
neering staff members was formed to investigate the failure for 
cause and to recommend corrective measures. A final report is 
expected to include analyses and possible solutions to this 
maintenance problem whereby the reliability of the equipment 
can be improved . 

CHERRY DAM HOI, LOW JET VALVE RliPAIRS 

The Machine Shop repaired one of the two 60 -inch valves used to 
release water from Lake Lloyd. The valve was leaking badly and 
water had gotten into the operating mechanism. If allowed to 
remain in place, it would have been necessary to replace the 
valve in a short period of time. It was necessary to build up 
and machine the body and plug seats, replace a brass bushing, 
a leather packing and two thrust bearings. Other miscellaneous 
repairs were made to broken or defective parts. The Mechanical 
I.ngineering Section provided engineering and procurement assis- 
tance to the Machine Shop, including inspection of work done to 
the plug seat by a local shop. At the end of the fiscal year, 
repairs were nearing completion and the valve will be available 
for use during the next runoff season. 

LARNER JOHNSON Rl iLI EF V A LVE N O. 2 AT SAN JOAQUIN VALVE HOUSE 

The relief valve on Pipeline No. 2 at the San Joaquin Valve 
House was removed from service during pipe cleaning and painting 
(HH-511R). The machine shop used this time to completely 
rebuild the valve including braising and remachining the seats.

Oril RAT I ON AND MAIN TEN ANCE - TRANSIT POWER DIVISION 

The Transit Tower Division is responsible for supplying the 600 
volt direct current power that is necessary to operate the 
strertcars and trolley coaches of the San Francisco Municipal 
Ra i 1 way . 

The Transit Power Division is composed of two sections - the 
Motive Power Section and the Overhead Lines Section. 

Motive Power Section 



11! 



The Motive Power Section operates and maintains seven sub- 
stations which convert electric power from 12,000 volts 
alternating current to 600 volts direct current by means of 
motor-generators, synchronous converters, and mercury arc 
rectifiers. (See Appendix Table 3 for statistical data.) 
Motive Power is also responsible for maintaining the electric 
motors and associated control equipment for operating the 
cable-winding machinery located in the Cable Car Powerhouse at 
Washington and Mason Streets. In addition, Motive Power does 
periodic inspection, cleaning, adjusting and repairing the 
streetcar and trolley coach recorders at Central Control of the 
Municipal Railway. The substations operate 24 hours per day, 
36 5 days per year. 

In anticipation of the need to assume responsibility for eigh- 
teen new substations, this section perused and commented on the 
wiring and control schemes proposed for these stations. 

A new mimic board showing the new stations in schematic form 
was constructed and installed at the Rryant Substation. As new 
automatic stations are completed and become operational, they 
will be monitored and controlled from this remote location. 
Since Outer Mission and West Portal Stations are presently 
unmanned, controls for these stations were designed and 
installed on this new mimic hoard. This new status display 
and control board will continually be augmented with new 
automatic station controls until such time as it shall be super- 
seded by a more sophisticated and flexible Supervisory Control 
System. 

Overhead Lines Section 

The primary function of the Overhead Lines Section is to main- 
tain in satisfactory operating condition the trolley wire over- 
head facilities and the electric distribution system which 
conveys power to it. This electric distribution system consists 
of both overhead lines and underground cables. 



17 - 



Secondary functions include the maintenance of the Municipal 
Railway Signal Systems and the electric light and power systems 
of all Municipal Railway buildings. 

During the fiscal year 1975-76, the Overhead Lines Section 
responded to 3606 emergency calls. In addition to emergency 
calls, this section had a regular and extensive maintenance 
program for overhauling all overhead and underground facilities. 
This section operated with three shifts per day, seven days a 
week. Monday through Friday, the normal workday shift was from 
8:00 a.m. to 3:30 p.m. with a two-man emergency crew on the 
"swing" or evening shift (3:30 p.m. -10:30 p.m.) and the grave- 
yard shift (1:00 a.m. -8:00 a.m.). 

On Saturdays, Sundays and holidays a two-man emergency crew was 
available on each of the three eight-hour shifts; midnight to 
8:00 a.m., 8:00 a.m. to 4:00 p.m., and 4:00 p.m. to midnight. 
Overhead and underground facilities were systematically 
inspected, and worn or damaged parts were replaced before they 
could cause accidents or malfunction of equipment. 

A considerable amount of damage to overhead facilities was 
caused by trolley coaches de-wiring and snagging their poles in 
the overhead facilities and tearing them down, or by breaking 
the spans with the flaying poles. Such damage was repaired at 
no cost to the Municipal Railway. Other parties who damaged 
our facilities were billed for the cost of repairs. This 
included damage to overhead facilities caused by high loads on 
trucks or careless operation of crane equipment and damage to 
underground feeder cables by contractors digging into our duct 
lines. During 1975-76, responsible parties were billed for 7 
damage cases totalling $3,728.53. The Overhead Lines Section 
also performed work for building owners and contractors under 
work orders amounting to 18 jobs totalling $44,183.13. This 
work included moving trolley poles to accommodate driveways; 
relocating trolley poles and feeders to permit construction of 
new buildings; temporarily removing trolley wires and feeders 
to permit passage of high loads: and shifting of trolley wires 
and feeders for various excavations. 

The Overhead Lines Section engaged in many other activities of 
a related nature which it is especially equipped to perform. 
These additional, duties included repairs, maintenance and 
construction of electrical systems in Muni's car barns, offices 
and shops ; welding and rebuilding of worn overhead lines special 
work; making and rebuilding parts for switches, warning block 
signals, car recorders, and strand alarms for the cable car 
system; installing mobile radio equipment; installing streetcar 
and bus stop signs and public information signs. 

In Marcli 1976 the section curtailed operations for a six week 
period during a labor dispute involving city Craft workers.

ENGINE ERING DIVISION 

The Engineering Division of Hetch Hetcliy Water and Power provides 
engineering services for the Hetch Hetchy Project and the Transit 
Power Division. These services include the preparation of 
studies, reports, cost estimates, and plans and specifications 
for new construction, for replacement of structures and for items 
of major maintenance. Surveying, inspection of construction, 
contract administration and payment recommendations are provided 
for all construction work under Hetch Hetchy Water and Power. 
Work of unusual magnitude or which requires special knowledge 
and expertise is done by engineering consulting firms which have 
the necessary manpower and qualifications. The Engineering 
Division is organized into five main sections: Structural and 
Civil, Electrical, Mechanical, Architectural, and Construction. 

During the year, plans and specifications were prepared for the 
following work to facilitate and maintain Hetch Hetchy operations: 

III' -4 5 4 - Reconstruct Moccasin Sewage Disposal System. 

A package sewage treatment plant producing an odorless effluent 
and sludge has been planned to replace the existing septic tank 
system. This project is a carryover from last year due to the 
slowness to acquire approval for the Federal "Clean Water Grant" 
which we reapplied for last year. Conceptual approval has been 
received. The EIR and the Project Report received approval from 
the State Water Resources Control Board, and we are now awaiting 
Federal EPA approval. The Hughes site for the effluent sprinkler 
field was purchased during the year. 

HH-4 77 - Moccasin Penstock Valve House. 

A contract was let for the construction of a steel frame struc- 
ture to enclose the butterfly valves at the head of Moccasin 
Penstock. This structure will provide protection and security 

for the valves. 

HH- 511R - San Joaquin Pipeline No. 2, Repair Lining. 

A contract was let for cleaning the interior of the pipe and 
applying a coal-tar lining. This work was necessary because 
the existing cement mortar lining, which protects the steel pipe 
from corrosion, has been softened by action of the soft water 
and the invert is being eroded away. 

HH-512 - San Joaquin River Valve House, Repairs and Piping. 

Under this contract, which was completed during the year, new 
sump pumps and related piping were installed at the San Joaquin 
River Valve House. Also, under this contract, a leaking manifold 
at the valve house was repaired.

HH- 51 4 - Moccasin Administration Building, Replace Heating 
System. 

The plans and specifications to replace the existing oil burning 
steam heating system and bring the electrical service at the 
building up to code were completed and bids opened this year. 
The existing heating system had become expensive to maintain 
and operate because of its age and its use of fuel oil. The 
replacement of the oil by electric heating necessitated increas- 
ing the capacity of the building electrical system, and improv- 
ing it to meet code requirements.

BUREAU OF LIGHT, HEAT AND POWER 

S TREET LIGHTING 

General 

The lighting of public streets within the City of San Francisco 
is provided by facilities which are, on a City-wide basis, 43.51 
owned by the City; 54.7s owned by the Pacific Gas and Electric 
Company; and a small percentage, 1.81, jointly owned. In the 
underground areas, where the economic advantage of City ownership 
is greatest, 81.31 of the lights are City-owned. Five years ago, 
the corresponding figure was 74.41. 

In fiscal year 1933-34, the cost for street lighting was $1.25 
per capita; last year, with approximately thirty times as much 
light on the~streets a n d public thoroughfares, the cost per 
capita was approximately $1.85. ~ 

Maintenance and repair of City-owned installations was performed 
under two contracts. One provided for group replacement of 
lamps in accordance with schedules developed by the Bureau. A 
second contract covered work required for repair of damaged and 
defective equipment, painting and miscellaneous maintenance. 

Under contract, the Pacific Gas and Electric Company furnished 
street lighting service as directed, including the furnishing, 
maintenance and operation of Company-owned facilities. Certain 
services were provided also for City-owned facilities, including 
switching and control, replacement of individual lamps and 
globes, and emergency work required during other than normal 
working hours. 

Electric energy for all City and Company-owned streetlight opera- 
tion was supplied by the Hetch Hetchy power system. 

Engineering 

The Bureau reviews, recommends changes, approvals or rejections 
of, and correlates all street lighting installations, including 
that done by the Department of Public Works, the Pacific Gas and 
Electric Company, the State of California, subdividers , etc. 

During the fiscal year 1975-76, 19 street lighting contracts, 
involving a total of 819 new streetlights, were approved by the 
Public Utilities Commission. Plans were submitted only after 
careful checking to determine that illumination will exceed the 
minimum requirements established by the American National 
Standards Institute; and that all materials used, and manner of 
installation, meet with the applicable local, state and federal 
rules, regulations and statutes governing the installation of 
electrical works.

BUREAU OF LIGHT, HEAT & POWER 
REVENUES AND EXPENDITURES 



FISCAL YEAR 1975-1976 



Operation and Maintenance 

As of June 30, 1976, a total of 37,378 City-owned and Company- 
owned streetlights were in service to the public streets, parks, 
viaducts, overcrossings , tunnels and underpasses. A summary of 
the number and type of units in service at the end of the fiscal 
year is shown in Appendix Table. 

A total of $1,326,226 was expended for operation, maintenance, 
and repair of the street lighting system. Of the total cost, 
$12,649 was paid by the State for its share of the operation and 
maintenance of street lighting at intersections on City streets, 
which are part of the State Highway system. 

During the fiscal year, there were 114 accidents involving damage 
to City-owned street lighting property. Investigation was made, 
as soon as possible, to remove hazards to the public and obstruc- 
tions to traffic. Total cost of repairs to damaged City-owned 
street lighting property was $73,125. Every effort was made to 
secure reimbursement for damages incurred from responsible 
parties. Previous experience indicates that approximately three- 
fourths of the repair costs will be recovered. 

Complaints 

During the year, 48 complaints requiring field investigation 
were received and acted upon. These complaints concerned 
inadequate illumination, objectionable glare in windows, and 
requests for temporary and permanent relocation of street 
lighting poles. 

Improvements 

During the fiscal year 1975-76, a total of 868 new City-owned 
streetlights were placed in service at a cost of $724,798. 
Improvements were financed by State Gasoline Tax and the 1964 
and 1972 Street Lighting Bond Issues as indicated in Appendix 
Tables 16 and 17.

U TILITY SERVICES TO MUNICIPAL DEPARTMENTS 

General 

Electric energy supplied to municiapl departments is generated 
on the Hetch Hetchy power system and delivered to various service 
points by transmission and distribution facilities of Pacific 
Gas and Electric Company under a wheeling contract. Natural gas 
supplied to municipal departments is furnished by the Pacific 
Gas and Electric Company under a service contract. 

Municipal Consumption of Electricity and Gas 

During the fiscal year, 486,936,786 kilowatthours of electrical 
energy were consumed through 1,054 municipal accounts at an 
expenditure of $6,077,738. Of the above, 147,463,469 kilowatt- 
hours of energy were supplied to the San Francisco International 
Airport for resale to tenants. Natural gas consumption was 
17,787,179 therms through 556 accounts at a cost of $2,691,890. 

There were several increases in gas rates last year which 
increased the cost to municipal accounts by approximately 
$805,652. The average cost per therm increased by approximately 
421. 

A summary of consumption and expenditures for these commodities 
is shewn in Tables 12 and 13.

O'SHAUGHNESSY DAM AND HETCH HETCHY RESERVOIR 
showing the effects of the drought in February, 1977. 



HIGHLIGHTS 

From the parched Redwood forests of the north state to the blazing 
deserts of the south, the one single aspect that dominated all of 
the water and power systems in California during the fiscal year 
is an unprecedented drought and its devastating impact. For the 
Hetch Hetchy Water and Power System, whose hydroelectric genera- 
tion is totally dependent on water, and whose viability as a going 
concern is principally dependent on power revenue, the year has 
been a particularly difficult one financially. 

The drought had its beginning in the winter of 1975-76 when lack 
of precipitation and meager snowmelt resulted in only 605,388 
acre-feet of runoff into Hetch Hetchy Reservoirs during the spring 
of 1976, or 53 percent of normal. The second dry year, 1976-77, 
resulted in even less runoff during the past spring, totaling only 
333,504 acre-feet, or 29 percent of normal. These record low 
inflows in successive years have left the three reservoirs in our 
mountain watersheds at less than 45 percent of capacity at the 
end of the report year. 



1 - 



Anticipating that the drought might continue into a second year, 
the Lower Cherry Aqueduct was reconditioned in the fall of 1976 
in the event that water supply to the Hetch Hetchy Aqueduct would 
need to be supplemented with water from Cherry Reservoir. This 
turned out to be a farsighted move when drought conditions dic- 
tated shutting down Dion R. Holm Powerhouse and diverting this 
water into the aqueduct to the Bay Area in October 1976. 

To further conserve water in our reservoirs against future public 
need, a request was submitted to the Secretary of the Interior, 
in March 1977, for permission to reduce fish releases from 
0' Shaughnessy Dam. So far, the Secretary has not advised us of 
any decision in the matter. 

Based on the precipitation record for the water year commencing 
October 1, 1976, and the result of snow surveys conducted on our 
mountain watersheds, the San Francisco Public Utilities Commission 
instituted a mandatory 25 percent reduction in system water 
consumption. The reduction was put into effect May 1, 1977, in 
order to insure the ability of the Hetch Hetchy systems to meet 
the needs of the San Francisco Water Department and its service 
area during the continuing drought. 

Comparing the amount of electric energy generated this year against 
that of previous years, the adverse impact of the drought is 
apparent. As generation was reduced to about 35 percent of normal, 
the resulting revenue available for supplying the cash flow for 
operating and maintaining the department was also reduced in 
roughly the same proportion. This necessitated rescinding many of 
the capital improvement projects scheduled for the year. 

In spite of the above, work progressed on the federally assisted 
Power Improvement Program for the rehabilitation of the Municipal 
Railway transit power system. As of the end of the fiscal year, 
approximately $26.5 million has been expended or encumbered. The 
professional services contracts for engineering design are 90 per- 
cent completed. Twenty-seven contracts for construction work and 
material purchases have been completed and twenty-two are currently 
in progress. Electrification of the Market Street Subway and Twin 
Peaks Tunnel is nearly completed. Ten of the eighteen substations 
are under construction, with three completed and in service. 
Thirty miles of the eventual fifty miles of underground duct lines 
are completed or under construction. Approximately 35 percent of 
the underground feeder cable has been installed, and an additional 
20 percent is on order for delivery to current installation 
contractors. The conversion of the streetcar overhead trolley 
system for pantograph operation is progressing with all work on 
the "K" Line under construction; the "N" Line ready for bid; and 
the "J", "L" and "M" Lines in the final design stages.

HETCH HETCHY ORGANIZATION AND FUNCTIONS 

Under policies established by the San Francisco Public Utilities 
Commission, the HETCH HETCHY WATER AND POWER DEPARTMENT and the 
BUREAU OF LIGHT, HEAT AND POWER serve the City and County of 
San Francisco in the dual function of operating department and 
service bureau. 

Hetch Hetchy is a municipally-owned system of storage reservoirs 
and aqueducts which collects water from the Tuolumne River water- 
shed and delivers it to the San Francisco Water Department. As 
a by-product of falling water, Hetch Hetchy operates and maintains 
hydroelectric generating stations and high voltage transmission 
lines for the production and distribution of electric energy. 

Through its Transit Power Division, Hetch Hetchy has funded, 
operated, maintained and provided improvements for the electric 
facilities of the San Francisco Municipal Railway since July 1, 
1969. 

In order to handle this additional responsibility, Hetch Hetchy 
assumed control of the equipment and personnel of the Overhead 
Lines and Motive Power Sections of the Municipal Railway. 

All of Hetch Hetchy' s expenses, including those of the Transit 
Power Division, are supported by water and power revenues. 

The Bureau of Light, Heat and Power administers contracts for 
furnishing electric, gas and steam services to municipal depart- 
ments and handles monthly billings. It also administers contracts 
for furnishing street lighting services and for operation and 
maintenance of City-owned street lighting. Financing, design and 
construction of City-owned street lighting improvements are under 
the jurisdiction of the Department of Public Works, and plans for 
these improvements must be approved by the Public Utilities 
Commission through this Bureau. The Bureau is financed by appro- 
priations from municipal departments and gas tax funds. 

For fiscal year 1976-77, the Department administered budgeted 
funds for all purposes as follows:

HI-TCH HETCHY WATER AND POWER SYSTEM 



REVENUE AND EXPENDITURES 



Revenue from Hetch Hetchy Water and Power operations is derived 
principally from two sources: 

1. Sale of water to the San Francisco Water Department 

2. Sale of electric power and energy to San Francisco Municipal 
departments, Modesto and Turlock Irrigation Districts in the 
San Joaquin Valley, and seven industrial customers: 

Kaiser Cement § Gypsum Corporation Santa Clara County 

Kaiser Aluminum § Chemical Corporation Santa Clara County 

Lockheed Missiles and Space Company, Inc. Santa Clara County 

General Motors Corporation Alameda County 

IBM Corporation Santa Clara County 

Liquid Air, Inc. Alameda County 

Norris Industries, Riverbank Stanislaus County 

WATER SALES 

This past year, revenue from the sale of water and standby service 
to the San Francisco Water Department was $8 million. 

POWER SALES 

Gross sale of electric energy was $43,341,973, up from $19,693,525 
during 1975-76. This doubling of revenue is deceiving, since the 
increase does not represent extra return on project investments 
for the following reasons: 

1. The increase is principally due to the record-breaking amount 
of supplementary power and energy which City had to purchase 
for resale, on account of the drought, and which was resold 

to the customers at substantially the same high price at which 
it was purchased. 

2. The offset to this year's so-called record revenue, in terms of 
expenditure for supplementary power and energy, is $33,921,500 
instead of the $2,100,000 budgeted, leaving only $9,420,473 in 
net revenue from gross, a far cry from the record net of over 
$18 million for 1974-75. 

Power and energy delivered to City Departments increased 2.0 per- 
cent over the previous year, about the same rate as in 1975-76. 
The City department mainly responsible for this increase is the 
San Francisco International Airport. Consumption at the Airport, 
the single largest energy consumer among the City Departments,

HETCH HETCHY REVENUES 

AND EXPENDITURES 

FISCAL YEAR 1976-77 



has increased by 3.2 percent, indicative of a resurgence of 
construction and expansion activities. Requirements for the 
Municipal Railway appear to have increased by 9.5 percent over 
the previous year. This is not a valid comparison, of course, 
because of last year's low consumption due to shutdown of the 
public transportation system during the 38-day employees' strike. 

Power and energy delivered to Modesto Irrigation District, Hetch 
Hetchy's largest power customer, and to Turlock Irrigation District, 
the third largest, increased by 17.2 percent and 37.9 percent 
respectively this year. These increases are directly related to 
the drought. The storage in Don Pedro Reservoir, upon which the 
two Districts are dependent for generation and irrigation needs, 
has been going down steadily and the Districts have been extremely 
careful in using this precious and meager resource. Since Hetch 
Hetchy is in the same predicament, 86 percent of the power deliv- 
ered to the Districts by Hetch Hetchy had to be supplied from 
supplementary power and energy purchased from the Pacific Gas and 
Electric Company. 

Total generation of 710,002,000 kilowatthours for the report year 
from the project's three plants (the lowest production since 1969) 
amounts to 43 percent of the output of 1,640,471,000 kilowatthours 
in 1975-76. The financial strength of the Department resulting 
from this decline in electric energy generation has been severely 
impaired. If current conditions continue, additional shortfall 
in operating revenue in the upcoming fiscal year can be anticipated. 

Hetch Hetchy power is sold at cost to City Departments for munici- 
pal purposes, representing a saving to taxpayers for 1976-77 of 
approximately $4 million, compared to the cost if supplied by the 
local investor-owned utility at rates which include a "fuel cost 
adjustment" to account for the additional costs brought on by the 
unending price increases in oil, gas and coal fuel used for 
electric generation. Beginning September 1976, revised rates for 
Hetch Hetchy power, approved by the Commission on July 13, 1976, 
became effective for private consumers and municipal users. The 
higher rates boosted power revenue from these sources by nearly 
$1 million in the fiscal year. This is just another step in our 
continuing effort to base our power rates on the value of power 
in the market place, in order to maximize the return of the power 
that is produced from the Hetch Hetchy system. In a fiscal year 
where generation is at a record low, this increase helped to 
somewhat ease the economic dislocation brought on by the reduced 
generation.

sheds, in light of the lessons learned from the drought, the

REVENUE FROM SALE OF ELECTRIC ENERGY 



Department has been investigating the feasibility of a weather 
modification program. The goal is to increase precipitation by 
cloud seeding of appropriate storms in the area. Preliminary 
data indicate that our effort should be directed to the Cherry 
Watershed. As an initial step to bring this program to fruition, 
plans are under way to hire expert consultants for the preparation 
of an Environmental Impact Report. 

On October 22, 1976, the City and County of San Francisco, through 
the Public Utilities Commission, together with the Modesto and 
Turlock Irrigation Districts, submitted an "Amended Application 
for Preliminary Permit, Clavey-Wards Ferry Project" to the Federal 
Power Commission. The application was made in order that the City 
and the Irrigation Districts might secure and maintain priority 
for a license under the Federal Power Act. The proposed project 
consists of three small dams and related facilities designed to 
harness the unused power potential of the Tuolumne. They would be 
situated on the upper reaches of the river below the City's Dion R. 
Holm and Robert C. Kirkwood Powerhouses and upstream from Don 
Pedro Dam. It is estimated that the project has a capability of 
generating 400 megawatts of power as well as a new water supply of 
11,900 acre-feet. However, actual development will depend on the 
outcome of a study by federal agencies for possible inclusion of 
this portion of the river in the federal wild and scenic river 
system. 

OPERATION AND MAINTENANCE 

On Sunday, November 7, 1976, at approximately 0822 hours, the 
13,800 volt metal-clad switchgear unit through which power is 
supplied to the 2,500 kVA Ridge Line transformer from Generator 
No. 2 at Dion R. Holm Powerhouse failed during routine testing 
of a protective device. The failure resulted in destruction of 
the circuit breaker element and related appurtenances. However, 
service to the Ridge Line was promptly restored by connecting it 
to the Mather Line, which is supplied from Robert C. Kirkwood 
Powerhouse. Necessary replacements were purchased from General 
Electric and installed by Department personnel with final adjust- 
ment and testing performed by field engineers from General 
Electric. All work was completed and service to the Ridge Line 
reverted to Dion R. Holm Powerhouse on June 3, 1977. 



WATER PRODUCTION AND TRANSMISSION 

Precipitation recorded for the year at our measuring stations was 
52 percent of the long term average. Much of this amount fell 
during the normally dry summer months and did not run off.

OPERATION AND MAINTENANCE - TRANSIT POWER DIVISIO N 

The Transit Power Division is responsible for supplying the 600 
volt direct current power that is necessary to operate the street- 
cars and trolley coaches of the San Francisco Municipal Railway. 

The Transit Power Division is composed of two sections - the 
Motive Power Section and the Overhead Lines Section. 

Motive Power Section 

The Motive Power Section operates and maintains ten substations 
which convert electric power from 12,000 volts alternating current 
to 600 volts direct current by means of motor-generators, synchro- 
nous converters, mercury arc rectifiers and silicon rectifiers. 
(See Appendix Table 3 for statistical data.) Motive Power is 
also responsible for maintaining the electric motors and associated 
control equipment for operating the cable-winding machinery located 
in the Cable Car Powerhouse at Washington and Mason Streets. In 
addition, Motive Power periodically inspects, cleans, adjusts and 
repairs the streetcar and trolley coach headway recorders at 
Central Control of the Municipal Railway. The substations operate 
24 hours per day, 365 days per year. 

In anticipation of the need to assume responsibility for eighteen 
new substations being built by the Power Improvement Program 
(reported elsewhere in this report) , this section perused and 
commented on the wiring and control schemes proposed for these 
stations. The first of the new electrical substations, Civic 
Center Station, was placed in revenue service in December of 1976. 
A commissioning ceremony was held by Mayor George Moscone who 
dedicated this first station to the service of the citizens of 
San Francisco. 

A new mimic board showing the new stations in schematic form was 
constructed and installed at the Bryant Substation. As each new 
automatic station is completed and becomes operational, it will 
be monitored and controlled from this remote location via telephone 
lines. Since Civic Center, Church, Judah, Outer Mission and West 
Portal Stations are presently unmanned, controls for these stations 
were designed and installed on this new mimic board. This new 
status display and control board will continually be augmented 
with additional automatic station controls until such time as it 
shall be superseded by a more sophisticated and flexible Supervisory 
Control System. 

Overhead Lines Section 

The primary function of the Overhead Lines Section is to maintain 
in satisfactory operating condition the trolley wire overhead 
facilities and the electric distribution system which conveys 
power to it. This electric distribution system consists of both 
overhead lines and underground cables. 



-11 



Secondary functions include the maintenance of the Municipal 
Railway Signal Systems and the electric light and power installa- 
tions at all Municipal Railway buildings. 

During fiscal year 1976-77, the Overhead Lines Section responded 
to 3,943 emergency calls, an increase of 8 percent over the prior 
year. In addition to emergency calls, this section performed a 
regular and extensive ongoing maintenance program. All overhead 
and underground facilities were systematically inspected and all 
worn or damaged parts that could cause accidents or equipment 
malfunctions were replaced. This section also operates an 
emergency crew 24 hours a day year round, including all holidays. 
The main work crew normally worked on the day shift but occasion- 
ally was assigned to night work to overhaul facilities during the 
hours Muni trolleys and streetcars do not run. 

A considerable amount of damage to overhead facilities was caused 
by trolley coaches de-wiring and snagging their poles in the 
overhead facilities and tearing them down, or by breaking the spans 
with the flaying poles. Such damage was repaired at no cost to 
the Municipal Railway. Other parties who damaged our facilities 
were billed for the cost of repairs. This included damage to 
overhead facilities caused by high loads on trucks or careless 
operation of crane equipment and damage to underground feeder 
cables by contractors digging into our duct lines. During 1976-77, 
responsible parties were billed for 9 damage cases totaling 
$17,246.41. The Overhead Lines Section also performed work for 
4 building owners and contractors under work orders amounting to 
$2,994.82. This work included moving trolley poles to accommodate 
driveways; relocating trolley poles and feeders to permit construc- 
tion of new buildings; temporarily removing trolley wires and 
feeders to permit passage of high loads; and shifting of trolley 
wires and feeders for various excavations. 

The Overhead Lines Section engaged in many other activities of a 
related nature which it is especially equipped to perform. These 
additional duties included repairs, maintenance and construction 
of electrical systems in Muni's car barns, offices and shops; 
welding and rebuilding of worn overhead lines special work; making 
and rebuilding parts for switches, warning block signals, car 
recorders, and strand alarms for the cable car system; installing 
mobile radio equipment; installing streetcar and bus stop signs 
and public information signs.

Moccasin Sewage Treatment 
Plant 



A package sewage treatment plant 
has been planned to replace the 
existing septic tank system. This 
process is a carryover from last 
year due to the lengthy process 
required to obtain approval for a 
federal "Clean Water Grant". State 
and federal permission to begin 
preparation of final plans and 
specifications was given in Septem- 
ber, 1976. Approval of the final 
plans and specifications was ob- 
tained in March, 1977. The con-

Under this contract, completed during the year, the old heating 
system, using costly fuel oil, was replaced by a new electrical 
heating/ventilating system. In addition, extensive electrical 
improvements were made to bring the existing electrical system up 
to code requirements, and extensive plumbing and architectural 
improvements were also made. 

HH-54 9 - Bryant Substation and Power Control Center 

The Power Control Center (part of the Power Improvement Program 
described elsewhere in this report) was originally to be installed 
in the existing Bryant Substation building. When engineering 
investigations of this 1904 building revealed that it did not meet 
seismic standards, it was determined to construct a new building 
to house both the Control Center and the new substation. The 
Control Center portion of the building will accommodate the facili- 
ties for remote supervisory control of the eighteen new automatic 
substations that will provide electric power for the Municipal 
Railway. The design of the substation portion of the building 
was performed by our consultants under the Power Improvement 
Program. The design of the Power Control Center portion of the 
building has nearly been completed by Hetch Hetchy personnel. 
The design of the facility has received approval of the Art 
Commission and a City Planning Commission Environmental Impact 
Report determination of no significant effect on the environment.

BUREAU OF LIGHT, HEAT AND POWER 



STREET LIGHTING 



General 



The lighting of public streets within the City of San Francisco 
is provided by facilities which are, on a City-wide basis, 44.0 
percent owned by the City; 54.2 percent owned by the Pacific Gas 
and Electric Company; and a small percentage, 1.8 percent, jointly 
owned. In the underground areas, where the economic advantage of 
City ownership is greatest, 82.4 percent of the lights are City- 
owned. Five years ago, the corresponding figure was 78.3 percent. 

In fiscal year 1933-34, the cost for street lighting was $1.25 per 
capita; last year, with approximately thirty times as much light 
on the streets and public t horoughfares , the cost per capita was" 
approximately $2.18. 

Maintenance and repair of City-owned installations was performed 
under two contracts. One provided for group replacement of lamps 
in accordance with schedules developed by the Bureau. A second 
contract covered work required for repair of damages and defective 
equipment, painting and miscellaneous maintenance. 



Under contract, the 
and Electric Company 
street lighting serv 
rected, including th 
ing , maintenance and 
of Company-owned fac 
Certain services wer 
also for City-owned 
including switching

Engineering 

The Bureau reviews, recommends changes, approvals or rejections 
of, and correlates all street lighting installations, including 
that done by the Department of Public Works, the Pacific Gas and 
Electric Company, the State of California, subdividers, etc. 

During the fiscal year 1976-77, 14 street lighting contracts, 
involving a total of 664 new streetlights, were approved by the 
Public Utilities Commission. Plans were submitted for approval 
> only after careful checking to determine that illumination will 
exceed the minimum requirements established by the American 
National Standards Institute; and that all materials used, and 
manner of installation, meet with the applicable local, state and 
federal rules, regulations and statutes governing the installation 
of electrical works. 

Operation and Maintenance 

As of June 30, 1977, a total of 37,446 City-owned and Company- 
owned streetlights were in service to the public streets, parks, 
viaducts, overcrossings , tunnels and underpasses. A summary of 
the number and type of units in service, at the end of the fiscal 
year, is shown in Appendix Table 14. 

A total of $1,524,286 was expended for operation, maintenance, 
and repair of the street lighting system. Of the total cost, 
$18,773 was paid by the State for its share of the operation and 
maintenance of street lighting at intersections on City streets, 
which are part of the State Highway system. 

During the fiscal year, there were 127 accidents involving damage 
to City-owned street lighting property. Investigation was made, 
as soon as possible, to remove hazards to the public and obstruc- 
tions to traffic. Total cost of repairs to damaged City-owned 
street lighting property was $104,000. Every effort was made to 
secure reimbursement for damages incurred from responsible parties. 
Previous experience indicates that more than half of the repair 
costs will be recovered. 

Complaints 

During the year, 40 complaints requiring field investigation were 
received and acted upon. These complaints concerned inadequate 
illumination, objectionable glare in windows, and requests for 
temporary and permanent relocation of street lighting poles. 

Improvements 

During the fiscal year 1976-77, a total of 691 new City-owned 
streetlights were placed in service at a cost of $1,184,878. 
Improvements were financed by State Gasoline Tax and the 1964 
and 1972 Street Lighting Bond Issue as indicated in Appendix 
Tables 16 and 17.

UTILITY SERVICES TO MUNICIPAL DEPARTMENTS 

General 

Electric energy supplied to municipal departments is generated on 
the Hetch Hetchy power system and delivered to various service 
points by transmission and distribution facilities of Pacific Gas 
and Electric Company under a wheeling contract. Natural gas 
supplied to municipal departments is furnished by the Pacific Gas 
and Electric Company under a service contract. 

Municipal Consumption of Electricity and Gas 

During the fiscal year, 496,305,458 kilowatthours of electrical 
energy were consumed through 1,072 municipal accounts at an 
expenditure of $6,966,586. Of the above, 152,161,432 kilowatt- 
hours of energy were supplied to the San Francisco International 
Airport for resale to tenants. Natural gas consumption was 
17,174,388 therms through 560 accounts at a cost of $3,321,758. 

There were several increases in gas rates last year which 

increased the cost to municipal accounts by approximately 

$629,868. The average cost per therm increased by approximately 
28 percent. 

A summary of consumption and expenditures for these commodities 
is shown in Tables 12 and 13.

HETCH HETCHY WATER AND POWER DEPARTMENT 
ORAL L. MOORE - General Manager 



This report is respectfully dedicated to 
Hetch Hetchy employees, past and present, 
whose devoted and conscientious efforts 
have made possible these accomplishments 
for San Francisco. 



HIGHLIGHTS 

In spite of a very poor first half, resulting from drought, and in spite 
of rate limitations established by court order, Hetch Hetchy finished the 
year with record high power revenues, both as to gross and net after 
power purchases. 

Starting with less than half full reservoirs at the beginning of the year, 
a third dry year was very much a possibility. In order to create the 
necessary funding to carry on operations in the face of potentially record 
expenditures for purchased power, a substantial portion of the previously 
budgeted capital improvements was rescinded. With heavy rains and snows 
falling on our mountain watersheds throughout the winter, resulting in 
spring runoffs which turned out to be the second highest recorded in the 
last 60 years, the severe drought, which has impacted the Department's opera- 
tions during the past two years ( ended and was replaced with a situation 
where our powerhouses were scheduled for all-out generation during the last 
half of the Fiscal Year. Combined with decreased power demands of the 
Modesto and Turlock Irrigation Districts, the Increased generation permitted 
Hetch Hetchy to sell much of its power at market rates in the last 6 months. 
This enabled the Public Utilities Commission to transfer $6 million of the 
Department's year-end surplus to the General Fund. 

As noted later in the report, the remaining $3 million from this year's 
surplus is earmarked for a reserve fund for protection of the City against 
possible failure of current litigation involving Hetch Hetchy power rates. 

To illustrate the remarkable turn-around of the last 6 months, a few selected 
comparisons between the two halves of the year is revealing.

HETCH HETCHY ORGANIZATION AND FUNCTIONS 



Under policies established by the San Francisco Public Utilities Commission, the 
HETCH HETCHY WATER AND POWER DEPARTMENT and the BUREAU OF LIGHT, HEAT AND POWER 
serve the City and County of San Francisco in the dual function of operating 
department and service bureau. 

Hetch Hetchy is a municipally-owned system of storage reservoirs and aqueducts 
which collects water from the Tuolumne River watershed and delivers it to the 
San Francisco Water Department. As a by-product of falling water, Hetch Hetchy 
operates and maintains hydroelectric generating stations and high voltage 
transmission lines for the production and distribution of electric energy. 

Through its Transit Power Division, Hetch Hetchy has funded, operated, maintained 
and provided improvements for the electric facilities of the San Francisco 
Municipal Railway since July 1, 1969. 

In order to handle this additional responsibility, Hetch Hetchy assumed control 
of the equipment and personnel of the Overhead Lines and Motive Power Sections 
of the Municipal Railway. 

All of Hetch Hetchy' s expenses, including those of the Transit Power Division, 
are supported by water and power revenues. 

The Bureau of Light, Heat and Power administers contracts for furnishing electric, 
gas and steam services to municipal departments and handles monthly billings. 
It also administers contracts for furnishing street lighting services and for 
operation and maintenance of City-owned street lighting. Financing, design and 
construction of City-owned street lighting improvements are under the juris- 
diction of the Department of Public Works, and plans for these improvements 
must be approved by the Public Utilities Commission through this Bureau. The 
Bureau is financed by appropriations from municipal departments and gas tax 
funds. 

For fiscal year 1977-78, the Department administered budgeted funds for all 
purposes as follows:

HETCH IIETCIIY WATER AND POWER SYSTEM 



REVENUE AND EXPENDITURES 



Revenue from Ketch Hetchy Water and Power operations is derived principally from 
two sources: 

1. Sale of water to the San Francisco Water Department 

2 . Sale of electric power and energy to San Francisco Municipal departments, 
Modesto and Turiock Irrigation Districts in the San Joaquin Valley, and seven 
industrial customers: 



Kaiser Cement & Gypsum Corporation 

Kaiser Aluminum & Chemical Corporation 

Lockheed Missiles and Space Company, Tnc, 

General Motors Corporation 

TRM Corporation 

Ltnuid Air, Inc. 

Norris Industries, Riverbank 



Santa Clara County

WA TER SALES 

This past year revenue from the sale of water and standby service to the San 
Francisco Water Department was $7,175 million 

POWER SALES 



Cross sales of electric energy was 49,971,915 t and increase of 6,629,942 from 
the $43,341 ,973 for 1976-77. The increase, by itself, appears substantial, but 
the significance of the increase goes beyond these numbers for the following 
reasons; 

(1) The offset to this year's power revenue in terms of expenditure for 
supplementary power and energy is $29,561,113, down from $33,921,500, 
leaving a net revenue from gross of $21,123,114 for the year as compared 
to $9,420,473 for 1976-77. This new high in net revenue replaced the 
record $18 million achieved in 1974-75. 

(2) The increase was achieved through the sale of power and energy 
generated during the months of March through June 1978 when all 
project plants were in maximum production in order to take full 
advantage of the record inflow and, at the same time, to delay filling 
of the reservoirs, thus minimizing spill. 

Power and Energy delivered to the City Departments decreased 2.1 percent over 
the previous year. The City department mainly responsible for this decrease is 
the San Francisco Water Department whose consumption dropped 31.3 per cent. Due 
to the effectiveness of both voluntary and mandatory water rationing programs 
during the drought, there wan considerably less need for pumping and filtration

of the domestic water supply. On the other side of the ledger, consumptions 
of the Municipal Railway and the Unified School District for the year have 
increased 7.5 per cent and 5 . 5 per cent respectively. The increase incurred 
l>y the Municipal Railway Is directly related to the completion of the John M. 
Woods Motor Coach Center and the Muni Metro Center, major facilities for the 
storage and maintenance of motor coaches, streetcars and eventually the new 
light rail vehicles. The magnitude of the increase incurred by the schools 
(including the community colleges) is uncharacteristic of the load based on 
historical records. A concerted effort in energy conservation might provide 
the key to reducing this groving consumption. Besides the San Francisco Water 
Department, consumption at the San Francisco international Airport also 
decreased 1.8 per cent as compared to previous year. In the face of continuing 
construction activities, this decrease seems to imply that energy conservation 
practices by both managment and tenants might be bearing fruit. 

Power and energy delivered to Modesto Irrigation District, perennially Hetch 
Hetchy 's largest power customer, and to Turlbck Irrigation District, normally 
the third largest but for 1977-78 the second largest, dropped 1.2 per cent and 
2.6 per cent respectively this year. These decreases are directly related to 
the dramatic ending of the drought which enabled the two Districts to supply 
during the last 6 months over 244 million kilowatthours of energy from their 
own generation as compared to 31 million kilowatthours in the first 6 months. 
Total generation of 1,401,610,000 kilowatthours for the report year from the 
project's three power plants represents a doubling of the 710,002,000 kilowatthours 
for 1976-77 which had the unenviable distinction of being the lowest production 
year since completion of the expanded system in 1969. The financial Impact of 
the additional generation can best be demonstrated by a comparison of the sales 
to the assigned industrial customers which are billed at current PCandE rates: 
^pro kilowatthours for 1976-77 versus 210 million kilowatthours for 1977-78, 
producing a revenue gain of $7.7 millions. 

Two conflicting rulings rendered by U.S. District Court judges during the year 
have affected our revenue from sale of Hetch Hetchy power. Both cases center 
on the question whether prior approval of the Secretary of Interior is required 
for rates charged by the San Francisco Public Utilities Commission for sale of 
Hetch Hetchy generated power for commercial purposes. On September 15, 1977 
Judge Cecil Poole, U.S. District Court for the Northern District of California, 
rendered a summary judgment in favor of City in the case of City and County of 
San Francisco vs. Various Airlines. Judge Poole ruled that the San Francisco 
Public Utilities Commission has the legal right to set rates for Hetch Hetchy 
power without approval of the Secretary of the Interior. The matter came to 
issue when the Public Utilities Commission, following historical practice, 
raised power rates to those prevailing in the service area in July 1975. The 
airlines initially refused to pay, contending that Hetch Hetchy power rates 
must be approved by the Secretary. On February 8, 1978. Judge Phillip Wilkins, 
U.S. District Court for the Kastern District of California, rendered two 
decisions in the case of the Modesto and Turlock irrigation Districts vs. City 
and County of San Francisco. The case was initiated by the two Districts in 
response to City's withdrawing of Class 3 Power (commercial power) from them 
on July 1, 1976.

RFVFNIIF FROM SAI F OF Fl Ff.TRir. FNFRfiY 



In favor of the City, the Judge held that the right of City to withdraw Class 
3 Hetch Hetchy power and substituting it with power purchased from PGandE 
involves a threshhold question of contract interpretation which, by virtue of 
the arbitration clause in the contracts, must be referred to arbitration. 
Against the City is the decision that the Secretary of the Interior must approve 
Hetch Hetchy power rates and the City therefore is restrained from selling Hetch 
Hetchy power for commercial purposes to any purchaser at rates not approved by 
the Secretary. Notices of appeal have been filed by opponents of the decisions. 
Even with the two cases now consolidated on appeal, resolution of the issues 
appears a long way down the road. 

Meanwhile, a reserve fund of $6,125 million is being established from this year's 
remaining surplus and the anticipated surplus for 1978-79 to protect the City 
from a substantial liability should the pending litigation be resolved against 
the City. 

Hetch Hetchy power is sold at cost to City Departments for municipal purposes, 
representing a saving to taxpayers for 1977-78 of approximately $8 million, 
compared to the cost if supplied by the local investor-owned utility at rates 
which include a "fuel cost adjustment" to account for the high costs of non- 
renewable fuels used for electric generation. 

In a continuing effort to maximize return of the power produced from its own 
system, Hetch Hetchy increased its rates for private consumers and municipal 
users to the level of current market value on July 1977 and again on April 1978. 
These increases would have more than doubled power revenue from the San 
Francisco International Airport - from about $3 million a year to $6.9 million. 
However, due to Judge Wilkin's decision as noted above, such hopeful gain was 
not achieved. Under guidelines suggested by the City Attorney's office while 
the injunction is being appealed, billing to the Airport tenants must revert 
to the Pre- July 1, 1975 rates beginning with the month of March 1978. 

SY STEM PLANNING 

As mentioned in the annual report last year about plans for initiating a weather 
modification program in the Cherry watershed area to increase its water yield, 
the City on December 1977 entered into a professional services contract with 
Environmental Science Associates, Inc., Foster City, California, for the 
preparation of an Environmental Impact Report. Steady progress is being made 
on the report draft, with approximately 30 per cent completed as of the end of 
the fiscal year.

WATLR PRODUCTION AND TRANSMISSION 

Precipitation recorded for the year at our measuring stations was 159% of the 
long term average. 

During the year, 51,935, 400, 000 gallons of water were diverted from the 
Tuolumne River watershed through the Iletch lletchy Aqueduct to the San 
Francisco Water Department, representing 78% of the City's total customer 
consumption. In addition, 199,7)3,204 gallons, down 9% from last year, 
were delivered to the United States Atomic Energy Commission at Mocho 
Shaft of the City's Coast Range Tunnel for use at the Lawrence Radiation 
Laboratory at Livermore; 49,932,740 gallons, down 15% from 1976/77, were 
delivered to Groveland Community Service District in Tuolumne County from 
the Mountain Tunnel. 

Appendix Table 6 shows comparative data on precipitation, runoff, storage 
and delivery of the Iletch lletchy Water Supply System.

DELIVERIES OF WATER TO 
SAN FRANCISCO WATER DEPARTMENT 



OPERATION AND MAINTENANCE - TRANSIT POWER DIVISION 

The Transit Power Division is responsible for supplying the 600 volt direct 
current power that is necessary to operate the streetcars and trolley coaches 
of the San Francisco Municipal Railway. 

The Transit Power Division is composed of two sections - the Motive Power 
Section and the Overhead Lines Section. 

Motive Power Section 

The Motive Power Section presently operates and maintains sixteen substations 
which convert electric power from 12,000 volts alternating current to 600 volts 
direct current by means of motor-generators, synchronous converters, mercury 
arc rectifiers and silicon rectifiers. (See Appendix Table 3 for statistical 
data.) Motive Power is also responsible for maintaining the electric motors 
and associated control equipment for operating the cable-winding machinery 
located in the Cable Car Powerhouse at Washington and Mason Streets. In 
addition, Motive Power periodically inspects, cleans, adjusts and repairs the 
streetcar and trolley coach headway recorders at Central Control of the 
Municipal Railway. The substations operate 24 hours per day, 365 days per year. 

In anticipation of the need to assume responsibility for the eighteen new 
substations being built by the Power Improvement Program (reported elsewhere 
in this report) , this section perused and commented on the wiring and control 
schemes proposed for these stations. The first of the new electrical 
substations, Civic Center Station, was placed in revenue service in December 
of 1976. Subsequently, in fiscal year 1977-78, nine new substations were 
placed in service: Downtown, Church, Judah, Fillmore, Carl, San Jose, Randolph, 
Taraval and Laguna Honda. 

A mimic board showing the new stations in schematic form was modified to 
incorporate these new stations at the Bryant Substation. As each new automatic 
station was completed and became operational, it was monitored and controlled 
from this remote location via telephone lines, since all the new stations are 
presently unmanned. The controls for these stations were designed and installed 
on this mimic board. This status display and control board will continually 
be augmented with additional automatic station controls until such time as it 
shall be superseded by a more sophisticated and flexible Supervisory Control 
System. 

Overhead Lines Section 

The primary function of the Overhead Lines Section is to maintain in satisfactory 
operating condition the trolley wire overhead facilities and the electric 
distribution system which conveys power to it. This electric distribution system 
consists of both overhead lines and underground cables. 

Secondary functions include the maintenance of the Municipal Railway Signal 
Systems and the electric light and power installations at all Municipal Railway

During fiscal year 1977-78, the Overhead Lines Section responded to 3,649 
emergency calls, a decrease of 8% over the prior year. In addition to emergency 
calls, this section performed a regular and extensive ongoing maintenance pro- 
gram. All overhead and underground facilities were systematically inspected and 
all worn or damaged parts that could cause accidents or equipment malfunctions 
were replaced. This section also operated an emergency crew 24 hours a day 
year round, including all holidays. The main work crew normally worked on the 
day shift but occasionally was assigned to night work to overhaul facilities 
during the hours Muni trolleys and streetcars do not run. 

A considerable amount of damage to overhead facilities was caused by trolley 
coaches de-wiring and snagging their poles in the overhead facilities and 
tearing them down, or by breaking the spans with the flaying poles. Such damage 
was repaired at no cost to the Municipal Railway. Other parties who damaged 
our facilities were billed for the cost of repairs. This included damage to 
overhead facilities caused by high loads on trucks or careless operation of crane 
equipment and damage to underground feeder cables by contractors digging into 
our duct lines. During 1977-78, responsible parties were billed for 11 damage 
cases totaling $6,946.34. The Overhead Lines Section also performed work for 
19 building owners and contractors under work orders amounting to $23,587.32. 
This work included moving trolley poles to accommodate driveways; relocating 
trolley poles and feeders to permit construction of new buildings; temporarily 
removing trolley wires and feeders to permit passage of high loads; and shifting 
of trolley wires and feeders for various excavations. 

The Overhead Lines Section engaged in many other activities of a related nature 
which it is especially equipped to perform. These additional duties included 
repairs, maintenance and construction of electrical systems in Muni's car barns, 
offices and shops; welding and rebuilding of worn overhead lines special work; 
making and rebuilding parts for switches, warning block signals, car recorders, 
and strand alarms for the cable car system; installing mobile radio equipment; 
installing streetcar and bus stop signs and public information signs.

EN GINE ERING DIVISION 

The Engineering Division of Hetch Hetchy Water and Power provides engineering 
services for the Hetch Hetchy Project, Transit Power Division and the Power 
Improvement Program. These services include the preparation of studies, 
reports, cost estimates, and plans and specifications for new construction, 
for replacement of structures and for items of major maintenance. Surveying, 
inspection of construction, contract administration and payment recommendations 
are provided for all construction work under Hetch Hetchy Water and Power. 
Work of unusual magnitude or which requires special knowledge and expertise is 
clone by engineering consulting firms which have the necessary manpower and 
qualifications. The Engineering Division is organized into six main sections: 
Civil and Construction, Electrical, Mechanical, Architectural, Engineering 
Administration, and Special Projects (Power Improvement Program). 

During the year, plans and specifications were prepared for the following work 
to facilitate and maintain Hetch Hetchy operations: 

HH-549 - Bryant Sub s tation and Po wer Control Cente r (Under Power Improvement 
Program) 

Plans and specifications for the Bryant Substation and Power Control Center, 
"Construct Building and Install Equipment", was completed in January 1978. 
Hetch Hetchy Water and Power and our consultants, Bechtel Incorporated have 
jointly prepared the plans and specifications. The Power Control Center portion 
of the building was exclusively designed by Hetch Hetchy. The building will 
be constructed on vacant City property, located adjacent to the existing 
Bryant Substation. The substation will supply 615 volt D.C. traction power 
to Municipal Railway trolley coaches. The Power Control Center will accommodate 
facilities for a shop, offices, and a power system supervisory control room. 

The PUC received bids on March 2, 1978, and the responsible low bid of $1,020,000 
submitted by Moore Construction of San Francisco was approved and the contract 
was awarded by PUC on March 14, 1978. Construction commenced in June 1978 and 
completion of project is scheduled for July 1979. The Bryant Substation and 
Power Control Center will complete the new substation construction program 
under the Power Improvement Program (PIP) . 

HH-566 - San Joaquin Valve Hou se - Backfl ow P revention and Replacement of 
Miscel laneous Mech anical Work 

Contract documents were prepared to prevent contaminated and polluted river 
water in Elliott Cut from entering the pipelines when they are drained for 
maintenance purposes in this area. The contract also includes the replacement 
of certain mechanical appurtenances at the valve house, Oakdale meter house 
and on the pipelines. 

HH-57_0 -_Surf ace West Portal an d Priest Roads 

A construction contract was let to resurface and seal the service roads into 
West Portal and Priest Reservoir to prevent the further deterioration of these 
roadways .

HV1-577 - OakdaleJ?ortal Sand Trap 

Plans and specifications have been prepared to construct a sand and gravel 
trap in the existing manifold which connects the San Joaquin pipelines to the 
Foothill Tunnel. The pipelines are being subjected to unusual wear along the 
invert of the pipes, caused by sand and gravel carried from the tunnel into 
these pipes. This contract will eliminate this source of wear to the pipelines. 

HH- 591 - Che rry Ro ad Slide Re pair 

Plans and specifications were prepared for repairing a slide area on Cherry 
Road near Cherry aqueduct tunnel portal 2-A by stabilizing the downhill slope 
and by excavating into the upslope bank to relocate a portion of the roadway 
away from the slide area. 

HH -593 - Pa i nt and Re p ai r D own t own Substation (Under Power Improvement Program) 

Plans and specifications have been prepared for the painting and repairs to 
the existing substation building. Work includes carbon-dust debris removal 
from building surfaces that was produced by the old rotary generators. 

Existing large windows on Stevenson Street will be elevated for added security. 

Interior and exterior painting and installation of additional lighting fixtures 
will complete the work on this operational substation. 

H H-595 - Moc cas i n S ewage Pla nt, Repla ce San i tary Sewer 

Plans and specifications were prepared and a contract let for replacing a 
portion of the sanitary sewer in Moccasin Village which has deteriorated badly 
over the years. Construction is scheduled to start in July 1978. 

Moccasin Powerhouse, Turbine and Bypass Bulkhead Gates. A purchase contract 
was let for the fabrication of structural steel gates which are required so 
that inspection or maintenance work can be performed in the discharge side 
of either unit separately, while the other unit remains in service. At 
present, both units must be shut down to accomplish this work. Bids were 
received in November 1977 with the gates to be delivered in July 1978.

During the months of February and March, the Foothill Tunnel and San 
Joaquin Pipelines were shut down for inspection. The following 
observations were reported: 

Moccasin Re-regulating Reservoir 

The bypass pipe is in good condition. The entrance to the Foothill 
Tunnel and Moccasin gate tower slide gate are in good condition, showing 
very little leakage with the reservoir elevation at 916. 0(+). 

Red Mountain Bar Wasteway 

The slide gate is in good condition. The concrete mortar lining D/S of 
the gate had eroded in a number of places but were repaired during the 
shutdown. 

Foothill Tunnel - Red Mountain Bar Wasteway to Oakdale Portal 

The Tunnel from Rock River Lime Treatment Plant to Red Mountain Bar is 
in good condition; no slides nor blockages, but some water infiltration. 
The Tunnel from Rock River Lime Treatment Plant to Oakdale Portal is in 
excellent condition, with no new slides or blockages. Some infiltration 
water into the Tunnel was noted and measured to be approximately 38 cfm. 
The sand trap at Oakdale Portal surge shaft had collected no appreciable 
amount of snad and the bulkhead was removed. 

San Joaquin Pipelines 

Pipeline No. 1 - The mortar lining was in good condition, showing no 
erosion nor deterioration on the invert section with less than 1/16 in. 
depth of the lining showing signs of "dead" mortar. 

Pipeline No. 2 - The lining in this pipeline shows considerable deteriora- 
tion since the last inspection three years ago. Some of this changed 
condition is due to the cleaning attempts performed under HH Contract 511-R. 
Areas of "dead" mortar have been removed along with small pieces of lining 
adjacent to cracks and previous bare metal spots. The coal tar paint 
east of Oakdale is doing an adequate job of protecting the mortar lining. 

Pipeline No. 3 - The mortar lining on the invert of the line has eroded 
to a width of 14 in. to 18 in. ; along this trough there remains a maximum 
of 1/4 in. mortar and in much of the area bare metal has been exposed. 
The remaining lining shows some deterioration due to leaching cement from 
the mortar by the pure water from Hetch Hetchy Reservoir. The outer 1/16 in. 
to 1/8 in. is "dead" mortar and can be removed by a single pass with a 
sharp metal object. Below this "dead" mortar, the remaining 3/8 in. to 
1/2 in. of lining is hard, sound mortar.

TrolLey Over hea d Program (TOP) 

The Public Utilities Commission has filled an application with the Department 
of Transportation, United States of America, for a grant under the Urban Mass 
Transportation Act of 1964, as amended, for a trolley coach overhead program 
for the San Francisco Municipal Railway. The program will be administered by 
Hetch Hetchy Water and Power since it is responsible for power distribution 
to Municipal Railway trolley coaches. The Trolley Overhead Program (TOP) will 
reconstruct and replace worn-out portions of the existing trolley coach system 
and construct trolley coach interconnections, turnarounds and traffic adjust- 
ments . 

The estimated cost of the program is $12,692,000 of which $10,153,600 (80%) 
will be funded by the Federal Government and $2,538,400 (207») will be funded 
from Hetch Hetchy revenues. 



In sta ll ation of D epth Sens or in Rock Riv er Shaf t o f Hetch Hetchy Aqueduct 

A transducer type depth sensor was installed in the Rock River Shaft of the 
Hetch Hetchy Aqueduct with a signal cable connecting the sensor to a digital 
readout indicator in the operator's office of the adjacent Lime Treatment 
Plant. This installation permits the Moccasin operator to telephone the 
operator of the Lime Treatment Plant and obtain the reading of the water 
level indicator. By knowing the water level at the Moccasin Reservoir and 
the water level at the Rock River Shaft, the flow in the aqueduct can be 
readily determined. Prior to the installation of the depth sensor, it was 
necessary to dispatch a man to the Oakdale Portal of the aqueduct to read 
the pressure gauge.

BUREAU OF LIGHT, HEAT AND POWER 



STREETLIGHTING 



General 



The lighting of public streets within the City of San Francisco is provided by 
facilities which are, on a City-wide basis, 44.2% owned by the City; 54.0% 
owned by the Pacific Gas and Electric Company; and a small percentage, 1.8%, 
jointly owned. In the underground areas, where the economic advantage of City 
ownership is greatest, 82.77., of the lights are City-owned. Five years ago, 
the corresponding figure was 80.27,. 

In fiscal year 1933-34, the cost for street lighting was $1.25 per capita; l ast 
H e §r , w i th ap proximately thirty t ime s _a s much 1 i gh t _o n th e streets and public 
thoroughfar es, the cost per cap ita was approximately $2.49 . 

Maintenance and repair of City-owned installations were performed under two 
contracts. One provided for group replacement of lamps in accordance with 
schedules developed by the Bureau. A second contract covered work required 
for repair of damaged and defective equipment, painting and miscellaneous 
maintenance. 

Under contract, the Pacific Gas and Electric Company furnished streetlighting 
service as directed, including the furnishing, maintenance and operation of 
Company-owned facilities. Certain services were provided also for City-owned 
facilities, including switching and control replacement of individual lamps 
and globes, and emergency work required during other than normal working hours. 

Electric energy for all City and Company-owned streetlight operation was 
supplied by the Hetch Hetchy power system. 

Engineering 

The Bureau reviews, reconmends changes, approvals or rejections of, and correlates 
all streetlighting installations, including that done by the Department of 
Public Works, the Pacific Gas and Electric Company, the State of California, 
subdividers, etc. 

During the fiscal year 1977-78, 10 streetlighting contracts, involving a total 
of 495 new streetlights, were approved by the Public Utilities Commission. 
Plans were submitted for approval only after careful checking to determine that 
illumination will exceed the minimum requirements established by the American 
National Standards Institute; and that all materials used, and manner of 
installation, meet with the applicable local, state and federal rules, regulations 
and statues governing the installation of electrical works.

UTIL ITY SERVICES _T0 MUNICIPAL DEPARTMENTS 
General 



Electric energy supplied to municipal departments is generated on the Hetch 
Hetchy power system and delivered to various service points by transmission 
and distribution facilities of Pacific Gas and Electric Company under a 
wheeling contract. Natural gas and steam supplied to municipal departments 
are furnished by the Pacific Gas and Electric Company under a service contract, 



Munic ipal Con sumpt ion of Ele ctri c ity, Gas and Steam 

During the fiscal year, 489,325,403 kilowatthours of electrical energy were 
consumed through 1,072 municipal accounts at an expenditure of $10,573,618. 
Of the above, 152,224,799 kilowatthours of energy were supplied to the San 
Francisco International Airport for resale to tenants. Natural gas 
consumption was 16,484,928 therms through 550 accounts at a cost of $3,623,447 

There were several increases in gas rates last year which increased the cost 
to municipal accounts by approximately $435,000. The average cost per therm 
increased by approximately 127». 

A summary of consumption and expenditures for these commodities is shown in 
Tables 12 and 13. 



- 28 - 



Op eration a nd Main tenance 

As of June 30, 1978, a total of 37,544 City-owned and Company-owned streetlights 
were in service to the public streets, parks, viaducts, overcrossings, tunnels 
and underpasses. A summary of the number and type of units in service at the 
end of fiscal year is shown in Appendix Table 14. 

A total of $1,740,591 was expended for operation, maintenance, and repair of 
the streetlighting system. Of the total cost, $22,631 was paid by the State 
for its share of the operation and maintenance of streetlighting at intersections 
on City streets, which are part of the State Highway system. 

During the fiscal year, there were 149 accidents involving damage to City-owned 
streetlighting property. Investigation was made, as soon as possible, to 
remove hazards to the public and obstructions to traffic. Total cost of repairs 
to damaged City-owned streetlighting property was $139,679. Every effort was 
made to secure reimbursement for damages incurred from responsible parties. 
Previous experience indicates that more than half of the repair costs will be 
recovered. 



C omp laints 

During the year, 39 complaints requiring field investigation were received and 
acted upon. These complaints concerned inadequate illumination, objectionable 
glare in windows, and requests for temporary and permanent relocation of street- 
lighting poles. 



Improvements 

During the fiscal year 1977,78, a total of 543 new City-owned streetlights were 
placed in service at a cost of $913,585. Improvements were financed by State 
Gasoline Tax and the 1964 and 1972 Streetlighting Bond Issue as indicated in
